I don't have any input regarding the code, but I have worked with IE 8. Not sure if that is an option, but if it is, they have a powerful script debugger that allows you to step through the code also.
Shawn >>> Max Stephan <x....@gmx.net> 08/28/09 8:24 AM >>> Hi Jerome, I´d be very happy if I could use Firebug in this case (very nice tool for debugging and for tracking the DOM in my opinion) but as I mentioned above: I´m using an ActiveX-Control for reading out the Access-Database and for sending further requests to it. And this method is only possible in Internet Explorer for which I haven´t found such a powerful debugging tool as firebug (firebug lite wasn´t useful). Ok, now here´s the loop, which is adding the vector-features to my vector-layer: for (var i=0; i<mestArray.length; i++){ addVector(vectorLayer, mestArray[i][1], mestArray[i][0]); } The first parameter is the target-layer, the second is a lonlat-object and the third is an attribute for the features. And here´s the addVector-function: function addVector(layer, lonlat, mestId){ var geometryObjekt = new OpenLayers.Geometry.Point(lonlat.lon,lonlat.lat); var vectorObjekt = new OpenLayers.Feature.Vector(geometryObjekt); vectorObjekt.attributes.mest = mestId; layer.addFeatures([vectorObjekt]); } And concerning your english: No need to be worried. I´m understanding everything.
